VACUUM RENOVATING APPARATUS.

To all whom it may concern:

Be it known that I, JOSEPH I-I. TEMPLIN a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Vacuum Renovating Apparatus, of which the following is a specification.

My invention relates in general to the construction of the well known portable vacuum renovating apparatus wherein the casing, with a cover for same, contains a vacuum reservoir, a separating device located in said vacuum reservoir, vacuum creating devices, and means for operating said devices, the whole combined into a form suitable to be carried or rolled from room to room, as desired.

My invention relates more particularly to the dust collecting devices, means for supporting the same, and their relative position to the inlets and passages for conveying the dust laden air into the dust collecting devices. r

The object of my invention is to arrange the inlets into the casing or vacuum chamber in a manner whereby the operator is enabled to see the dust laden air as it passes through a portion of said passages. The inner opening of said passage is so disposed that the dust laden air passes over the upper edge of the dust-collecting bag, said edge being sunken below the edge of the casing or vacuum chamber. With this construction, the cover of the casing or vacuum chamber can be removed or replaced without disturbing or interfering with the suction hose. i

I attain the above purposes of merit and convenience by the means illustrated in the accompanying drawings, in which similar letters of reference indicate like parts.

In the drawings, Figure 1 represents a side elevation of my improved vacuum renovating apparatus; Fig. 2 is a plan view of the same; Fig. 8 is a vertical longitudinal section of Fig. 1; Fig. 4 is a partial plan of casing and vacuum chamber; and Fig. 5 is a view on the line w-w of Fig. 1, showing the observation glass passageway and separating dust-bag ring in section.

Referring to the drawings, 1 represents the main casing of preferably rectangular form, 2 is a center, plate or floor hermetically sealed to the casing, and provided wlth the openings 3 for attaching to inlets of pumps.

4 1s a ring secured hermetically to the upper end of the casing 1, said ring 4 being provided with the inlet opening 5 at each end thereof, to which the suction hose end 76 is adapted to connect, said openings being closed when not in use.

The opening 5 at one side only will be described. This opening 5 connects with passage 6 preferably leading along the wide side of the casing, and turning abruptly upward toward the inside of the casing at 7, permitting the dust-laden air to pass to its receptacle. At some point in sa1d pas-. sage 6 I haveprovided a seat to receive a transparent plate of glass, celluloid or the like, 9, said plate 9 being secured to its seat by cement 10 (see Fig. 1), or by a plate 11 ig. 5) and gaskets 13 and 14 and suitable securing means. The ring 4 is also provided with studs 16 which project upward and accommodate quick-actin clamps 17 which are secured onto said studs 16.

18 is a cover adapted to rest upon the top of ring 4:, with the packing gasket 19 interposed, said cover 18 being provided with slots 20 which aline withclamps 17. When the clamps 17 stand in line with the slot 20, the cover is free to be put on or removed readily. With .the cover in place onequarter turn of clamp 17 in the direction of the threads of the stud 16 causes the inclined surfaces 21 on the clamp 17 to engage with similar inclined surfaces on the cover, thereby depressing the cover hard against the gasket 19 on top of ring 4, thereby hermetically sealing and forming the vacuum reservoir.

The separating device consists of one or more receptacles or bags of more or less porous material. In my illustration of the power machine, I have shown two bags. The outer bag 23 is secured to the inner side of the vacuum reservoir 1, and is preferably made of heavy material. The inner receptacle or dust bag 24 is made of somewhat coarser material than 23, and is designed to receive the dust and foreign matter that is delivered into it by the dust-laden air, and is adapted to be readily removed from the Specification of Letters Patent.

machine for emptying, cleaning and wash- .ing, if necessary.

. erably rubber) gas et 28, which extends beyond the edges of the metal flange, as shown. The flanged ring 25 sets into a flared pocket in ring 4 when in its normal position and the machine is ready for operation. The projections 29 in ring 4 regulate the location or depth of seating of said flanged ring 25. Located below the center plate or floor 2 is a suitable means for exhausting air from the reservoir, which means consists of a motor A and pumps B operated thereby, said pumps being connected to the inlet openings 3.

From the above description it will be apparent that I have provided a vacuum cleaner wherein the chamber leading from the inlet openings in the end wall extends transversely of the side wall, and has an outlet at its inner end into the reservoir, and that this outlet is above the supporting member for the dustreceptacle, which permits the cover to be removed without dist'urbing in any way the ipe connections through which the dust-la en air is drawn into the vacuum reservoir. Furthermore, this chamber through which the dust laden air is led has a glass in one wall thereof which'enables the operator to see the dustladen air as it passes through this portion of the chamber.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a vacuum cleaner, the combination of a vacuum reservoir having an inlet opening in the end wall thereof, a chamber formed on the inner wall of said reservoir and extending transversely of said wall and connecting W1th said opening, said chamber having an outlet at its inner end into the reservoir, a dust receptacle, a supporting member for said dust receptacle located adjacent the wall of said chamber below said discharge outlet thereof, a removable cover for said receptacle, and means for exhausting air from the reservoir.

2. In a vacuum cleaner, the combination of a vacuum reservoir having; an inlet in the end wall thereof adjacent the upper end of the reservoir, a chamber extending along one of the side walls of the reservoir on the inner face thereof and adjacent its up per end and connecting with said inlet opening, said chamber having an outlet at the opposite end from the inlet opening, the wall of the reservoir along saidchamber havinga side opening therein, a glass for closing said opening, a dust receptacle, a supporting member for said dust receptacle located adjacent said chamber and beneath the discharge opening thereof, a removable cover for said reservoir, and means for exhausting air from the reservoir.

In testimony whereof I affix my slgnature in presence of two w1tnesses.
